LTC7813EUH in Linear Tech / ADI LT Series Family
The LTC7813EUH family by Analog Devices (formerly Linear Technology) consists of high-performance dual-output synchronous DC/DC switching regulator controllers. It integrates a step-up (boost) controller and a step-down (buck) controller into a single package. These controllers are engineered to maintain a regulated output voltage during input voltage dips, such as automotive cold-crank scenarios, by cascading the boost and buck stages. Operating from an input up to 60V, it provides a highly efficient solution for multi-rail power management in demanding environments.
Variants in This Sub-Family
Variants within the LTC7813 sub-family typically differ based on their temperature grade and packaging requirements. The 'E' designation denotes an extended temperature range of -40°C to 125°C, while 'I' or 'H' grades offer higher thermal reliability for extreme environments. While the UH suffix refers to the 32-lead 5mm x 5mm QFN package, different suffixes may indicate lead-free finishing options or tape-and-reel quantities, though the core silicon performance remains consistent across the series.
